<h1>Upgrading from 1.2 to 1.3</h1>

<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.2.  If you
have not upgraded to that version please do so first.</p>


<p>Before performing an update you should take your site offline by replacing the index.php file
with a static one.</p>


<h2>Step 1: Update your CodeIgniter files</h2>

<p>Replace the following directories in your "system" folder with the new versions:</p>

<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>

<ul>
<li>application/<strong>models</strong>/&nbsp;&nbsp;  (new for 1.3)</li>
<li>codeigniter&nbsp;&nbsp;   (new for 1.3)</li>
<li>drivers</li>
<li>helpers</li>
<li>init</li>
<li>language</li>
<li>libraries</li>
<li>plugins</li>
<li>scaffolding</li>
</ul>


<h2>Step 2: Update your error files</h2>

<p>Version 1.3 contains two new error templates located in <dfn>application/errors</dfn>, and for naming consistency the other error templates have
been renamed.</p>

<p>If you <strong>have not</strong> customized any of the error templates simply
replace this folder:</p>

<ul>
<li>application/errors/</li>
</ul>

<p>If you <strong>have</strong> customized your error templates, rename them as follows:</p>


<ul>
<li>404.php&nbsp;&nbsp; =&nbsp; error_404.php</li>
<li>error.php&nbsp;&nbsp; =&nbsp; error_general.php</li>
<li>error_db.php&nbsp;&nbsp; (new)</li>
<li>error_php.php&nbsp;&nbsp; (new)</li>
</ul>


<h2>Step 3: Update your index.php file</h2>

<p>Please open your main <dfn>index.php</dfn> file (located at your root).  At the very bottom of the file, change this:</p>

<code>require_once BASEPATH.'libraries/Front_controller'.EXT;</code>

<p>To this:</p>

<code>require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;</code>


<h2>Step 4: Update your config.php file</h2>

<p>Open your <dfn>application/config/config.php</dfn> file and add these new items:</p>

<pre>
/*
|------------------------------------------------
| URL suffix
|------------------------------------------------
|
| This option allows you to add a suffix to all URLs.
| For example, if a URL is this:
|
| example.com/index.php/products/view/shoes
|
| You can optionally add a suffix, like ".html",
| making the page appear to be of a certain type:
|
| example.com/index.php/products/view/shoes.html
|
*/
$config['url_suffix'] = "";


/*
|------------------------------------------------
| Enable Query Strings
|------------------------------------------------
|
| By default CodeIgniter uses search-engine and
| human-friendly segment based URLs:
|
| example.com/who/what/where/
|
| You can optionally enable standard query string
| based URLs:
|
| example.com?who=me&what=something&where=here
|
| Options are: TRUE or FALSE (boolean)
|
| The two other items let you set the query string "words"
| that will invoke your controllers and functions:
| example.com/index.php?c=controller&m=function
|
*/
$config['enable_query_strings'] = FALSE;
$config['controller_trigger'] = 'c';
$config['function_trigger'] = 'm';
</pre>


<h2>Step 5: Update your database.php file</h2>

<p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p>

<pre>
$db['default']['dbprefix'] = "";
$db['default']['active_r'] = TRUE;
</pre>


<h2>Step 6: Update your user guide</h2>

<p>Please also replace your local copy of the user guide with the new version.</p>
